Answer:
It would take 3.11 J to warm 3.11 grams of gold
Explanation:
Step 1: Data given
Mass of gold = 3.11 grams
Temperature rise = 7.7 °C
Specific heat capacity of gold = 0.130 J/g°C
Step 2: Calculate the amount of energy
Q = m*c*ΔT
⇒ Q = the energy required (in Joules) = TO BE DETERMINED
⇒ m = the mass of gold = 3.11 grams
⇒ c = the specific heat of gold = 0.130 J/g°C
⇒ ΔT = The temperature rise = 7.7 °C
Q = 3.11 g * 0.130 J/g°C * 7.7 °C
Q = 3.11 J
It would take 3.11 J to warm 3.11 grams of gold
As far as I understand, you have to plot <span>t(v) = v/k.
According to this, you have to use a form like that </span>
, in which
.
Then you can see that the vertical-intercept is zero therefore the gradient should be is <span><span>1/k.
Do hope you will find my both answer helpful and useful. Regards!</span></span>
The answer is B. Forming bonds requires energy and breaking bonds releases energy. The transition state is the highest point in one reaction energy profile. Before the transition state, the energy increases which means transition state absorbs energy.
Answer:
B, C, F. and H
Explanation:
<em>The correct answer would be B, C, F, and H.</em>
According to the kinetic theory, the kinetic energy of molecules of a substance is directly proportional to the temperature of the substance.
<u>The intermolecular forces holding the molecules in a solid together become weaker as the temperature of the solid increases along with the kinetic energy. The molecules vibrate and further apart, leading to the melting of the solid.</u>
